I have considerable difficulty responding to general philosophical statements like this, so could someone provide me with a scenario in which individual autonomy actually threatens collective security?
Some examples of political subjects where individual autonomy and collective security come into conflict are rights or entitlements to: free speech, privacy, protest against the government, due process in law, practice ones faith, affiliate with groups of ones choice, not be conscripted, decide not to let soldiers use ones home in a time of war, to be in a minority group without being persecuted or marginalized from participation in civic life, sympathize with or assist enemies of the state, pollute the environment, operate heavy machinery while under the influence of drugs, drive an automobile while talking on ones cell phone, peaceful support for the overthrow of the government, low or non-existent taxes, individual access to welfare benefits when in need, etc.
